JAMES T. KENNEDY, OF PETERSBUR-G, TENNESSEE, ASSIGNOR OF ONE-HALF TO L.V. FOGLEMAN, OF SAME PLACE.

PLOW.

SPECIFIQATION forming part of Letters Patent No. 234,915, dated November30, 1880. 7 Application filed October 3, 1879.

To all whom it may concern Be it known that I, JAMES T. KENNEDY, ofPetersburg, in the county of Lincoln and State of Tennessee, haveinvented certain new and useful Improvements in Flows; and I do herebydeclare that the following is a full,

clear, and exact description of the invention,

which will enable others skilled in the art to which it appertains tomake and use the same, [0 reference being had to the accompanyingdrawings, which form a part of this specification.

Figure l is a perspective front view. Fig. 2 is a side elevation. Fig. 3is a view, in perspective, of the rear and under side of the plow. Fig.4 is a longitudinal vertical sectional view taken through the share andmoldboard. Fig. 5 is a view of the frame, the share and mold-boardhaving been detached; and Fig. 6 is a view of one of the shares.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to plows; and it consists in certain improvementsin the construction of the same, which will be hereinafter more fullydescribed, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the beam, and B thestandard. Suit- 3o ably secured to the latter is a frame, G, composed ofthe bars 0, G, and 0 the two latter being secured to the standard B, tothe outer edge of which is bolted one of the handles, D, the otherhandle, E, being secured to the land- 3 5 side F, which is also boltedto the standard, as shown. An S-brace, G, connects the lower ends of thehandles, the upper ends of which are connected in the usualmanner byrounds H.

In the construction of this plow two mold- 0 boards, or sections ofmold-boards, are employed, one of which is adjustable, so as to enablethe size of the plow to be altered at will to any desired number. Thesolid or permanent mold-board I is provided with a flange, 5 J, by whichit is bolted to the side of the standard in such a position as to coverthe frame 0. The movable mold-board K is adjusted between frame 0 andmold-board I, and is provided with two bolts, L L, sliding in frame 0,and holding a cross-piece, M,

which may be tightened up against frame 0, and thereby secure themold-board K in any desired position. The shape of the moldboards is, ofcourse, such that they will fit closely together in any position, andthe edge of the upper one is sloped down thin toward the lower one.

From this description it will be seen that the lower mold-board may beeasily adjusted, so as to present a surface of any desired size.Accompanying each plow is therefore a full set of diflerently-sizedshares, each of the shape represented in Fig. 6, and capable of beingsecured upon the point of the plow. To this end the frame 0 is providedwith a lip, N, hav- 6 5 ing a perforation adapted to receive a boltpassing through a perforation in the upper side of the share. The edgeof the share is provided with a similar perforation, enabling it to bebolted to the point of the standard. It will be readily seen from theforegoing description and by reference to the drawings hereto annexedthat by changing the share and adjusting the lower mold-board myimproved plow may be readily adjusted to any desired size.

I am aware that an adjustable mold-board is not broadly new, as oneconstructed in three parts is shown in the patent to Gibbs, No. 107,037,of September 6,1870, and I therefore make no broad claim to the same.

Having thus described myinvention, I claim and desire to secure byLetters Patent of the United States In a plow, the standard B,providedwith the frame 0 G 0 having lip N, and the stationary upper mold-board,I, in combination with the lower adjustable mold-board, K, having thecross-piece M secured to its under side by the screw-bolts L L,constructed and oper- 9o ating substantially as and for the purposes setforth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
